The Savuti Marsh is in Botswana. A channel from the Linyanti River once fed the now dry Savuti Marsh, which is the deepest part of the Mababe Depression and is the only part to have filled with water in recent history.
This marsh has something of a mystical renown as it can dry up or flood regardless of local rains. David Livingstone, on his way to 'discover' the Victoria Falls in 1851, commented, that it was a "dismal swamp," but sometime around 1888 it started to dry up and remained completely parched until 1957. Camelthorn acacia trees established themselves in the channel and along the banks and grew to full size. During unexpected floods these trees were drowned but as the channel and marsh dried out again, the dead trees became one of the most prominent features of the landscape.
